I think that this has been tried with some success but not alot. I would look at Tom Sanfords work on the SAM missile. You can find it at SimV.
look through these...
maybe from them you can figure it out. I do know that there is a thrust and MACH limit that CFS2 will not go past. Which is one reason why many attempts at a Vietnam expanion have been dropped. As far as CFS3 goes, well it may or may not have the same issue.
